Sketch released in fatal shooting of twin

Four months after Coty Beavers was found shot to death, and 14 months since his twin brother's girlfriend died in an unsolved shooting, the Harris County Sheriff's Office released a sketch of a man seen asking about Beavers days before his death.

The Sheriff's Office and the Houston Police Department have downplayed theories that the deaths are connected. In a news release Thursday, Sheriff Adrian Garcia's office said neither agency has uncovered any evidence that would link Beavers' killing to that of his twin's girlfriend, 30-year-old Gelareh Bagherzadeh. She was shot to death near her Galleria-area townhouse.

According to the release, the man in the sketch, who has dark hair, thick eyebrows and glasses, is considered a person of interest. A witness saw him asking about Beavers at his apartment complex, near the Sam Houston Tollway on the northwest side, just days before he was found dead at home with multiple bullet wounds.

His killing on Nov. 12 rocked twin Cory Beavers, family and friends who were still mourning Bag­herzadeh's unexplained death, which sparked speculation she was killed because of passionate comments opposing the Iranian government and her 2011 conversion to Christianity.

Friends and family hoped a January memorial on the one-year anniversary of her death would rekindle interest in solving the case, for which Crime Stoppers has offered its biggest reward ever: $200,000.

Crime Stoppers is offering a $5,000 reward for information leading to an arrest and charges in Coty Beavers' case. Call the Sheriff's Homicide Unit at 713-967-5810.

To share information in Bagherzadeh's death, call the HPD Homicide Division at 713-308-3600, or Crime Stoppers at 713-222-TIPS.
